Herein, originally from Italy, though housed in the USDOE's National Laboratory library, we present a discussion about the productive recycling of Carbon Dioxide, as might originate in an industrial process utilizing Coal.
The premise, in confirmation of other documentation attesting to CO2 recycling potentials we have already provided you, is that CO2 can be used as a "substitute" raw material, in place of other chemicals, such as the highly-toxic Phosgene (aka: Mustard Gas), in the manufacture of useful, and common, plastics.
And, as interesting as such practical use of CO2 might be, these Italian scientists make a point that, due to the awkwardness of translation, might be missed:
Not only can Carbon Dioxide be productively utilized in place of other, some highly-toxic, materials, such practical use of Carbon Dioxide prevents the generation of more Carbon Dioxide in the commercial manufacture of those other raw materials.
